Regime 2: Transitional

 

As noted earlier, in the transitional regime the effects of free molecular heat transfer and conduction can be considered to occur in series. So, the heat transfer coefficient can found by combining contributions from 1 and 3 as follows:

$${ \frac{1}{H_{g}} = \frac{1}{H_{fm}} + \frac{1}{H_{ct}}}$$
